Use a floating Red Hat Go Toolset tag.
Line 1 selects a build-qualified tag. The default builder will not track later Red Hat-managed updates unless this line changes. Use the supported floating tag for the required Go 1.26 stream.
As per path instructions, “Red Hat images: use floating tags (Red Hat manages updates).”

Make Go 1.26.6 the enforced minimum.
Line 5 suggests Go 1.26.6, but the unchanged go 1.26.0 directive sets the minimum. With GOTOOLCHAIN=local, Go uses its bundled toolchain, so a Go 1.26.5 installation can still build this module. The Go documentation distinguishes the suggested toolchain version from the required go version. (go.dev)
Set the go directive to 1.26.6, or add an explicit version check to every build entrypoint. This makes the older-toolchain failure described in the PR objective enforceable.

The shipped image's binary was built with go1.26.5, which leaves 8 Important Go stdlib CVEs open (CVE-2026-56860, -33818, -46600, -56858, -56862, -56853, -56859, -39821), all fixed in Go 1.26.6. Raise the go directive to 1.26.6 so a builder below the CVE floor fails the build instead of silently producing a vulnerable binary. The go directive is what enforces this: the Konflux builder sets GOTOOLCHAIN=local, under which the toolchain directive is ignored entirely and only the go directive is checked. go mod tidy drops the now-redundant toolchain line. Also switch the BASE_IMAGE default to the floating ubi9/go-toolset:1.26 tag so local `make build-image` tracks Red Hat's z-stream updates rather than drifting behind, which is how the previous 1.26.3 pin fell four z-streams below CI. Konflux overrides BASE_IMAGE via build-args and already resolves to go1.26.7. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Hey @diakovnec , how about we use a tag like 1.26.7-1790174511? Though 1.26 shall point to the latest, having a specific tag can avoid cache which may still use an older 1.26 version.

The binary in our shipped image was built with Go 1.26.5. That release has 8 Important CVEs in the standard library, all fixed in 1.26.6:
CVE-2026-56860, -33818, -46600, -56858, -56862, -56853, -56859, -39821
Nothing in the repo prevented this. go.mod asked for go 1.26.0, so any toolchain from 1.26.0 up was accepted, and whatever the builder happened to have is what we shipped.
The fix
go.mod: raise the go directive to 1.26.6.
This is a hard floor. Any toolchain older than 1.26.6 now refuses to build the module, so we can't accidentally ship a vulnerable binary again — the build fails instead.
go.mod: drop toolchain go1.26.5.
That line did nothing useful and one harmful thing. Konflux builds with GOTOOLCHAIN=local, which ignores the toolchain directive entirely — so it was never going to stop a bad build. Meanwhile developers building locally use the default GOTOOLCHAIN=auto, where the line is honoured, and it was telling Go to fetch exactly the release carrying these CVEs.
build/Dockerfile: change the BASE_IMAGE default to the floating ubi9/go-toolset:1.26.
It was pinned to 1.26.3-1780490420, which is how it went stale in the first place. The floating tag tracks the 1.26 stream, so make build-image locally stays close to what CI produces. Konflux overrides this anyway via build-args and currently resolves to go1.26.7.
